For convenience of description, the direction in which the hard seal 8 moves relative to the flexible seal 7 during installation will be referred to as the first direction.
Specifically, the moving directions of the first matching surface 5 and the second matching surface 6 are opposite, as shown in fig. 2, when the matching surface of the middle frame 2 forms the first matching surface 5 and is provided with the flexible sealing member 7, and the matching surface of the speaker 4 forms the second matching surface 6 and is provided with the hard sealing member 8, during installation, the first matching surface 5 and the flexible sealing member 7 are not moved, and the second matching surface 6 drives the hard sealing member 8 to move towards the installation cavity relative to the first matching surface 5, at this time, the first direction is an outside-in direction along the depth direction of the installation cavity, and along with installation of the speaker 4, the hard sealing member 8 has a tendency of scraping the flexible sealing member 7, and enables the flexible sealing member 7 to move towards one side in the installation cavity relative to the first matching surface 5; as shown in fig. 6, when the second mating surface 6 is formed on the mating surface of the middle frame 2 and provided with the hard sealing member 8, and the first mating surface 5 is formed on the mating surface of the speaker 4 and provided with the flexible sealing member 7, during installation, the second mating surface 6 and the hard sealing member 8 are not moved, and the flexible sealing member 7 is driven by the first mating surface 5 to move relative to the second mating surface 6, at this time, the first direction is a direction from inside to outside along the depth direction of the installation cavity, and along with installation of the speaker 4, the hard sealing member 8 has a tendency of scratching the flexible sealing member 7 and making the flexible sealing member 7 move to one side outside the installation cavity relative to the first mating surface 5.
In order to avoid the situation that the hard sealing element 8 generates a rubbing effect on the flexible sealing element 7 and the position of the flexible sealing element 7 moves to cause incapability of matching in the relative fitting and sliding process before the flexible sealing element 7 and the hard sealing element 8 are matched, in this embodiment, as shown in fig. 3 and 7, the first matching surface 5 is provided with a mounting groove 52, the mounting groove 52 is arranged along the circumferential direction of the first channel 51, the mounting groove 52 is used for mounting the flexible sealing element 7, specifically, when the first direction is the direction from outside to inside along the depth direction of the mounting cavity, as shown in fig. 3, a limiting structure 54 is formed on one side wall of the mounting groove 52 facing the inside of the depth direction of the mounting cavity, as shown in fig. 4, when the flexible sealing element 7 is mounted in the mounting groove 52, the limiting structure 54 can limit the movement of the flexible sealing element 7 relative to the first matching surface 5, so that the position of the flexible sealing element 7 is stable in the mounting process of the loudspeaker 4, and the flexible sealing element 7 and the loudspeaker 4 can be matched with the hard sealing element 8 after the loudspeaker 4 is mounted in place. (ii) a When the first direction is a direction from inside to outside along the depth direction of the mounting cavity, as shown in fig. 7, a side wall of the mounting groove 52 facing the outside of the depth direction of the mounting cavity forms a limiting structure 54, as shown in fig. 8, when the flexible sealing element 7 is mounted in the mounting groove 52, the limiting structure 54 can limit the flexible sealing element 7 to move relative to the first mating surface 5, so that the position of the flexible sealing element 7 is stable during the mounting process of the loudspeaker 4, and the flexible sealing element 7 and the hard sealing element 8 can be matched after the loudspeaker 4 is mounted in place.
Moreover, as shown in fig. 2 and fig. 6, the matching surfaces of the middle frame 2 and the speaker 4 are both inclined surfaces that are adapted to each other, and specifically, the top end (the end facing the opening of the installation cavity) of the matching surface of the middle frame 2 is inclined to the side outside the installation cavity, that is, the sectional area of the opening end of the installation cavity is larger than the sectional area of the bottom end, so that when the speaker 4 is installed, because the space of the opening end is large, the matching surface of the speaker 4 does not contact with the matching surface of the middle frame 2 at first, and before the speaker 4 is installed in place, a gap still remains between the matching surface of the speaker 4 and the matching surface of the middle frame 2, the hard sealing element 8 and the flexible sealing element 7 are not completely matched, the speaker 4 can be installed smoothly, and contact sliding between the two matching surfaces and between the hard sealing element 8 and the flexible sealing element 7 is reduced, so that the acting force of the hard sealing element 8 rubbing the flexible sealing element 7 is reduced, and the installation operation is facilitated, and the sealing protection effect after installation is ensured.
Therefore, in the electronic device provided in this embodiment, when the speaker 4 is installed in the installation cavity, the speaker 4 may be directly installed from outside to inside along the depth direction of the installation cavity, the speaker 4 does not need to be tilted, and the installation operation is relatively convenient, and meanwhile, the arrangement of the limiting structure 54 can also avoid that the relative position between the flexible sealing element 7 and the first installation surface 5 changes due to the rubbing action during the installation process, so as to ensure the sealing protection effect after the installation is completed, and meanwhile, the structure of the speaker 4 does not need to be changed, so as to ensure the sound output effect of the electronic device.
The depth of the installation groove 52 is not less than the thickness of the flexible sealing element 7, that is, the flexible sealing element 7 is entirely located in the installation groove 52 and does not protrude out of the first matching surface 5, meanwhile, the hard sealing element 8 protrudes out of the second matching surface 6, during installation, because the flexible sealing element 7 does not protrude out of the first matching surface 5, when the hard sealing element 8 slides along the first matching surface 5, the hard sealing element 8 cannot be scraped and rubbed against the flexible sealing element 7 until the two matching surfaces relatively move to the right position, the hard sealing element 8 is matched with the flexible sealing element 7, at this time, one side end of the hard sealing element 8 facing the first matching surface 5 can just enter the installation groove 52 and abut against and be matched with the flexible sealing element 7, and the sealing effect is ensured.
When the two mating surfaces are mated, the end of the hard sealing member 8 facing the first mating surface 5 may partially enter the mounting groove 52 and abut against the flexible sealing member 7, and a gap may be left between the two mating surfaces, or when the two mating surfaces are mated, the hard sealing member 8 may completely enter the mounting groove 52 and abut against the flexible sealing member 7, and the two mating surfaces are attached to each other.
In this embodiment, the depth of the mounting groove 52 may also be smaller than the thickness of the flexible sealing element 7, at this time, a part of the flexible sealing element 7 extends out of the mounting groove 52, that is, a part of the flexible sealing element 7 protrudes out of the first mating surface 5, when the hard sealing element 8 slides relatively along the first mating surface 5 during mounting, the flexible sealing element 7 protruding out of the first mating surface 5 can be cut and rubbed, but due to the limiting effect of the groove wall of the mounting groove 52, the position of the flexible sealing element 7 on the first mating surface 5 does not move, and the sealing protection effect after mounting in place can also be ensured.
Alternatively, in this embodiment, the limiting structure 54 may be formed by disposing a stopper (not shown) on the first mating surface 5, where the stopper is specifically disposed on one side of the flexible sealing member 7 facing the first direction, when the first direction is from outside to inside along the depth direction of the mounting cavity, the stopper is disposed on one side of the flexible sealing member 7 facing the mounting cavity, and when the first direction is from inside to outside along the depth direction of the mounting cavity, the stopper is disposed on one side of the flexible sealing member 7 facing the outside of the mounting cavity. Specifically, the stopper may be a protruding structure arranged at intervals or a continuous protruding structure, and the situation that the flexible sealing element 7 is scratched by the hard sealing element 8 and moves at the position of the first mating face 5 can be limited.
Compared with the arrangement of a stop block, the arrangement of the mounting groove 52 can simplify the overall structure, when the flexible sealing element 7 is completely arranged in the mounting groove 52, the hard sealing element 8 is not scratched mutually before being matched with the flexible sealing element 7 in the mounting process of the loudspeaker 4, the position stability of the flexible sealing element 7 is ensured, meanwhile, the mounting resistance between the first matching surface 5 and the second matching surface 6 can be reduced, and the mounting operation of the loudspeaker 4 is facilitated.
As shown in fig. 4 and 8, the flexible sealing member 7 is adhesively fixed to the inner wall (side wall and/or bottom wall) of the mounting groove 52 by the first adhesive layer 53, that is, the flexible sealing member 7 is adhesively fixed to the mounting groove 52. In this way, it can be further ensured that the flexible sealing member 7 can be stably positioned in the mounting groove 52, further ensuring the mounting stability. If the position-limiting structure 54 is a stopper disposed on the first mating surface 5, the flexible sealing member 7 and the stopper and/or the flexible sealing member 7 and the first mating surface 5 may be bonded and fixed by the first adhesive layer 53 to ensure the stability of the flexible sealing member 7.
Or, the flexible sealing element 7 may be directly placed in the mounting groove 52, when the depth of the mounting groove 52 is not less than the thickness of the flexible sealing element 7, the flexible sealing element 7 may be entirely located in the mounting groove 52, and there may be no other connection manner between the two, and when the flexible sealing element 7 is fixed by bonding through the first adhesive layer 53, the stability of the flexible sealing element 7 in the mounting groove 52 may be further ensured.
Of course, in this embodiment, the fixing manner of the flexible sealing member 7 is not limited, for example, the flexible sealing member 7 and the first mating surface 5 may be fixed by a fastener, and the adhesive fixing by the first adhesive layer 53 may simplify the overall structure and simplify the installation operation, and may further ensure the sealing function between the first mating surface 5 and the flexible sealing member 7.
